BACKGROUND OF THE INVENTION

People who seek to precisely shoot rifles long distances frequently record information on the adjustments required to hit targets at various distances and under various wind conditions. This information is frequently recorded on a “dope” (Data On Previous Engagement) card. Shooters, particularly hunters and competitive shooters, often need to locate this information very quickly. In a match, a shooter may have to hit four or more targets of various size and at various distances in not more than 90 seconds. Long range hunters may similarly face short time windows to shoot at game before the game moves out of view or rotate to an orientation which makes an ethical shot impossible. Therefore, a dope card is frequently placed in a location which is readily accessible to the shooter. Common locations are on a shooter's wrist or forearm, on a card taped to the stock of a rifle, on a shooting mat, and in a folder. Shooters also need to position certain other accessories in readily accessible locations. These accessories include but are not limited to, wind meters and laser range finders.

Once a shooter is positioned to shoot a rifle, moving one's head away from the stock to look at a dope card or accessory, and then re-position on a rifle, can take valuable time causing time to expire in competition or cause a shooter to no longer have an ethical shot when hunting. Rifles which are shot precisely are frequently configured with magnified optics in the form of a telescopic sight known as a scope. Such rifles are also frequently configured with features which allow accessories to be attached, such as with one or more sections of MIL-STD-1913 (Picatinny) rail.

DETAILED DESCRIPTION OF THE INVENTION

The applicant's invention is a novel apparatus for attaching an accessory to a firearm. The device is primarily defined by a shaft 1 attached at both ends to rotatable friction pivots. In a preferred embodiment, the device is configured to attach a dope card to a section of picatinny rail 2 on the top or side of a firearm. In an alternative embodiment, the device is configured to attach a dope card to a scope.

In a preferred embodiment, the shaft 1 is cylindrical. In a preferred embodiment, the shaft 1 is metal. In an alternative embodiment, at least a portion of the shaft 1 is polygonal with preferably radiused corners. In this embodiment, the shaft, or attachment, “ratchets” between indexed positions as it is rotated within the friction pivot.

An adjustable friction pivot is preferably comprised of multiple pieces. The friction pivot is comprised of a friction pivot shaft attachment member 3 configured to wrap around a shaft. The friction pivot shaft attachment member is configured with a flat surface. The flat surface of the friction pivot shaft attachment member 3 at one end of the shaft is configured to be parallel to a flat surface on a member 4 configured to attach, directly or indirectly, to a firearm. The flat surface of the friction pivot shaft attachment member 3 at the other end of the shaft is configured to be parallel to a flat surface on a member configured to attach to an accessory. The member configured to attach to a firearm 4 and the member configured to attach to an accessory 6 are collectively referred to as mating members. The friction pivot shaft attachment members 3 and mating members 4 and 6 are constructed of materials which provide a desirable coefficient of friction. In a preferred embodiment, each friction pivot shaft attachment member 3 is attached to its respective mating member by a screw 5 passing through the friction pivot shaft attachment member into threads in the mating member. The head of the screw 5 may be separated from the friction pivot shaft attachment member 3 by a washer 14. In certain embodiments, a deformable o-ring 14 selected of a material which provides a desirable coefficient of friction and degree of deformation is installed between the friction pivot shaft attachment member 3 and the mating member to achieve the desired coefficient of friction between the friction pivot shaft attachment member 3 and the mating member. In a preferred embodiment, the mating member is configured with the flat surface being further from the friction pivot shaft attachment than the top of the female threaded member. The distance between the top of the female threaded member and the flat surface of the mating member is selected such that the desired coefficient of friction is achieved when the screw 5 is tightened to the degree the end meets the bottom of the screw hole. In an alternative embodiment, the coefficient of friction between the friction pivot shaft attachment member and the mating member is also adjustable by tightening or loosening the screw 5 connecting the friction pivot shaft attachment member 3 to the mating member.

The friction pivot shaft attachment members 3 are configured to be rotatable around the shaft 1 on at least one end of the shaft. In a preferred embodiment, a portion of the shaft 1 is rebated 15 inside the connection with the friction pivot shaft attachment member 3 to prevent the friction pivot attachment member 3 from sliding off the shaft 1. The friction pivot attachment member 3 is made from a material and sized such that the coefficient of friction between the friction pivot attachment member 3 and shaft 1 generally resists rotation but can be rotated with the application of sufficient force.

In a preferred embodiment, the mating member configured to be attached to the firearm contains features configured to attach to a MIL-STD-1913 (Picatinny) rail. In a preferred embodiment, the Picatinny rail attachment features comprise a main body 4 and a clamping member 8 joined by a plurality of screws 9. In a preferred embodiment, the main body contains protrusions configured to fit in grooves in a Picatinny rail 2, a dovetail 12 configured to interface with the edge of a Picatinny rail 2, and a plurality of holes configured to accept the passage of screws. In a preferred embodiment the clamping member 8 is configured with a dovetail 13 configured to interface with the edge of a Picatinny rail 2 and a plurality of female threaded members 10, preferably a thread insert, configured to cooperatively interface with each of the plurality of screws 9. In a preferred embodiment, the screws 9, which pass through the main body 4 and thread into the clamping member 8, pass through depressions in the Picatinny rail and draw the clamping member 8 toward the main body 4 clamping the Picatinny rail 2 when tightened. In an alternative embodiment, the mating member configured to be attached to the firearm contains features configured to attach to a telescopic rifle scope or other accessory attachment standard including, but not limited to, Arca Swiss, M-LOK, KeyMod, Dovetail rail, Weaver rail, Warsaw Pact rail, UTI rail, Rail Integration System (RIS), and NATO Accessory Rail.

In a preferred embodiment, the mating member configured to be attached to the accessory 6 contains a substantially flat surface to which written material, such as a piece of paper approximately the size of a business card, can be attached. In certain embodiments, the flat surface contains a plurality of ears 11 on at least one side configured to hold a piece of paper in place against the flat surface. In an alternative embodiment, the mating member configured to be attached to the accessory contains other features configured to attach an accessory to the mating member.

The applicant's invention is preferably configured such that, under the force of recoil, the friction members to not rotate but under the application of sufficiently greater force then the force of recoil, such as pressing the rod against a door or window, the friction mount yields to the applied force and rotates, thereby reducing the likelihood of injury or damage posed by or to the device.
